Baghouse dust collector

At this time, the pulse control instrument of the pulse bag filter sends out a signal at regular intervals, opens the electromagnetic pulse valves in sequence, and can quickly send the compressed air bag through the holes on the spray gun, so that the ejector ejects a high flow rate through the filter bag. In this way, the filter bag can expand rapidly, and after blowing, the filter bag will shrink sharply. Analyze the working principle of the pulse bag filter: Such expansion and contraction can ensure that the filter bag is in a good working state. Since the ash cleaning process is carried out in sequence without cutting off the dust-laden air, the dust removal capacity remains basically unchanged during the operation of the pulse bag filter.

Analysis of the working principle of the pulse bag filter by the dust collector skeleton: In order to meet the requirements of different working conditions, the pulse control instrument can adjust the pulse interval and pulse width of the pulse bag filter at will. If the dust removal bag finds that the equipment resistance exceeds the limited range and the outlet, and there is obvious dust, inspection and adjustment can be carried out according to these methods. We can use the fault elimination method: let it run and see if it is because there is too much dust on the filter bag or because of electromagnetic valve failure. When there is a valve failure, the solenoid valve and the control system can be inspected, and the pipes can be cleaned and dredged. The coverage form should be reasonably selected according to the distribution type of pollution sources, process equipment, production operation conditions, etc., so that both can effectively control dust without affecting workers' operation and equipment maintenance.

To minimize vibration and rigid connections in reciprocating equipment, reduce openings and gaps in the cover to ensure a tight and secure enclosure. Necessary access ports, maintenance doors, and inspection ports should be provided according to process requirements. These openings must be airtight, easy to install, and allow smooth opening and closing of components. Minimize the total open area. Opening positions should be located away from positive pressure zones of the housing and areas with high air velocity. Generally, the operating temperature of pulse jet baghouse dust collectors must exceed the acid dew point temperature by at least 25K to ensure safe operation of the dust bags. This primarily prevents condensation when operating temperatures fall below the dew point, which can generate liquid water. Liquid water accumulating on the surface of dust-laden filter bags can form a paste-like bag.
